When using a key with an embedded picture once it is uploaded to SEMS the user does not have the opportunity to change back to pdf, or web email protection, or change keys.
As soon as you click any button in the UI it logs you out.
If you manually delete the key from the SEMS server UI function returns to normal.
This is not present if using a key without a picture ID.
Tested in 3.4.2 MP4, and 10.5
The development team is aware of this issue and taking steps to rectify it.
